Wastewater Monitoring Results for 2026-03-22
Published: March 26, 2026 · Period: 2026-03-22Wastewater monitoring provides an early signal of respiratory virus activity in the community. When people are infected, they shed viral genetic material in their feces and urine. This means wastewater data can show trends in infections even when individual testing rates change. This surveillance helps public health officials track the spread of viruses.
The most recent measurement shows Influenza B at 40.0 gene copies per liter and RSV at 26,680.0 gene copies per liter. Influenza A was not detected. Compared to the past 30 days, RSV levels are elevated, while Influenza B activity is present but lower. These levels do not indicate disease severity.
Two tables help interpret this data. One shows the combined activity over the last seven days, giving a snapshot of current conditions. The other compares current levels to historical annual peaks, providing long-term context. This helps show whether current measurements are unusual for the time of year.
A short glossary explains key terms. RSV, or Respiratory Syncytial Virus, is a common cause of respiratory illness. Influenza A and Influenza B are the two main types of flu virus. RNA is the genetic material of these viruses. PCR is a lab method used to detect and measure this RNA in wastewater.
